The need for 300 Hz electric power keeps on increasing on airplanes. Up to now the way how to obtain constant frequency from variable speed drive is either hydro or electro-mechanical. New conversion systems are arising: they take benefits from the most recent improvements and developments in high speed electrotechnics and power electronics. Rotational speeds running atmore than 24000 r.p.m. are now accessible to the on-board generator and consequently a significant improvement of power to weight ratio is obtained. The installation of such a generator on aircraft entails an high speed gear which can be combined with it or, better, installed in the accessory gearbox. The cooling of the whole system can be realized by air or, better, by oil, electronic components included. Optimum design leads to share the oil circuit of the gearbox with the generator cooling system.
